TECHNICAL FIELD

The present disclosure relates to fiber optic telecommunications devices. More specifically, the present disclosure relates to packaging arrangements for storage, shipping, and rapid deployment of fiber optic cables.

BACKGROUND

As demand for telecommunications increases, fiber optic networks are being extended in more and more areas. In facilities such as multiple dwelling units, apartments, condominiums, businesses, etc., fiber optic enclosures are used to provide a subscriber access point to the fiber optic network. These fiber optic enclosures are connected to the fiber optic network through subscriber cables connected to a network hub. However, the length of subscriber cable needed between the fiber optic enclosure and the network hub varies depending upon the location of the fiber optic enclosure with respect to the network hub. As a result, there is a need for fiber optic deployment packaging arrangements that can effectively manage varying lengths of subscriber cable. There is also a need for fiber optic cable storage, transport, and deployment packaging assemblies that utilize cost-effective, recyclable materials.

DETAILED DESCRIPTION

Reference will now be made in detail to the exemplary aspects of the present disclosure that are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like structure.

Referring now to FIGS. 1-7, a first embodiment of a deployment packaging arrangement 10 for fiber optic cabling is illustrated, the packaging arrangement 10 having features that are examples of inventive aspects in accordance with the principles of the present disclosure. The packaging arrangement 10 generally defines a plurality of spools 12, each configured for storing a loop of telecommunications cable 14 (e.g., fiber optic cable). Each spool 12 is formed from two opposing flanges 16 coupled together with a spool hub 18. The spool hub 18, once used to join the flanges 16, is positioned around a spindle 20. Once assembled, each of the spools 12 of the packaging arrangement 10 is individually rotatable with respect to the spindle 20 in winding and/or unwinding the cabling.

FIG. 1 illustrates a deployment packaging arrangement 10 that is formed from eight spools 12. It should be noted, depending upon the application needed, other numbers are possible. The packaging arrangement 10 is modular such that the number of spools 12 can be scaled up or down depending upon the desired need by using the appropriate length spindle 20. FIG. 2 illustrates a partially exploded view of one of the spools 12 of the packaging arrangement 10 of FIG. 1, the spool 12 shown with a cover 22 exploded therefrom. FIGS. 3-4 illustrate one of the flanges 16 defining the spools 12 of the packaging arrangement 10. The flanges 16 may be formed from molded polymers. FIG. 5 is a spool hub 18 for coupling two flanges 16 for forming a spool 12 as shown in FIG. 2. The spool hub 18 is frictionally fit into a hub receiver 24 of each flange 16 in forming the spool 12. FIG. 6 illustrates an example of a core or a spindle 20 that may be used to form the packaging arrangement 10 of FIG. 1. The spindle 20, according to one example embodiment, may be formed from cardboard tubing. The plurality of spools 12 of the packaging arrangement 10 are slidably disposed around the spindle 20 and each of the spools 12 is rotatable with respect to the spindle 20. FIG. 7 illustrates the cover 22 of one of the spools 12 in isolation. The cover 22 may also be formed from cardboard material. Thus, all of the major parts of the packaging arrangement 10 are formed from low cost, generally recyclable materials.

Referring now specifically to FIGS. 2-3, each flange 16 defining the spool 12 has a first side 26 that makes contact with the cable 14 (i.e., a cable-winding side) and a second opposite side 28 that defines a compartment 30 for storing a cable termination element 32 as will be described in further detail below. The storage compartment 30 is defined by a lip 34 that protrudes around the perimeter of the flange 16. As shown in FIG. 1, when the spools 12 are arranged on the spindle 20, the two second sides 28 of adjacent spools 12 face each other. Each flange 16 defines a plurality of reinforcement elements 36 that extend between the center spool hub receiver 24 and the outer perimeter of the flange 16.

As noted above, the storage compartment 30 defined by the second side 28 of the flange 16 may be used to store a termination element 32 that might be terminated to one end of the cable 14. A termination element 32 generally refers to any device that might be used to terminate the end of a cable 14 for further connectivity. An example of a termination element 32 might be a telecommunications connector 38 that is terminated to the cable 14. For example, the telecommunications connector 38 may be a fiber optic connector. The fiber optic connector 38 may be a multi-fiber optic connector such as an MPO connector 38, an example of which is shown in FIGS. 8-9. Another example of a termination element 32 might be a telecommunications device in the form of a fiber optic cassette 40 that is configured to branch out fibers coming from a multi-fiber cable 14 to separate connection locations. Such connection locations may be defined by fiber optic adapters 42 as will be described in further detail. An example of a fiber optic cassette 40 is shown in FIG. 11, the fiber optic cassette 40 defining SC type adapters 42 as the connection locations. Another example of a fiber optic cassette 40 a that defines LC type adapters 42 a is shown in FIG. 12.

Although the principles of the present disclosure will be described and illustrated in terms of cable termination elements 32 in the form of fiber optic connectors 38 or fiber optic cassettes 40, it should be noted that the principles herein may be applicable to others types of structures that may be terminated at the ends of the fiber optic cables 14 stored in the packaging arrangement 10.

Now referring to FIGS. 1, 2, and 7, once an end of a cable 14 (either preterminated or postterminated) has been passed through the flange 16 into the storage compartment 30, the cover 22 may be frictionally fit around the hub receiving portion 24 of the flange 16 to enclose the storage compartment 30. It should be noted that a cover 22 may be used at each end of the packaging arrangement 10 or may be used between each of the individual spools 12. The cover 22 may provide reinforcement and further rigidity to the flanges 16. The term “postterminated” refers to an end of a cable that is terminated with a device after the cable has been passed through an opening 44 of the flange 16 as will be described in further detail below.

As discussed above, during the initial assembly of the packaging arrangement 10, for each spool 12, one end of a cable 14, before that cable 14 is wound around the spool 12, is passed through one of the flanges 16 of the spool 12 and is contained within the storage compartment 30. The end that is passed through the flange 16 may be unterminated when initially winding the cable 14 around the spool 12 and may be terminated afterwards with a termination element 32 after passing that end through the spool 12. As shown in FIGS. 2-4, the flange 16 defines a passage or opening 44 that is large enough to pass an end of an unterminated cable 14 through the flange 16 from the first side 26 to the second side 28. Also, the flange 16 defines a scored section 46 which may be removed from the flange 16 if the end of the cable 14 that is passed through the flange 16 has been pre-terminated with a larger cable termination element 32. The scored portion 46 may also be removed after deployment once all of the cable 14 has been unwound when a post-terminated end needs to be passed from the second side 28 to the first side 26 of the flange 16 to completely remove the cabling from the spool 12.

In this manner, the flanges 16 provide options during packaging for the types of terminations that will be used in the packaging arrangement 10. Once the packaging has been assembled, the entire arrangement 10 may be placed within an outer box or enclosure during storage or transport. During deployment, the spindle 20 of the packaging arrangement 10 may be placed around a mandrel type device to facilitate rotating the spools 12.

Referring now to FIGS. 8-13, a method of fiber optic cable deployment utilizing a modular cable pulling system 48 that includes a plurality of cable termination elements 32 coupled together using a system of snap-fit carriers 50 for the termination elements 32 is illustrated. The modular cable pulling system 48 illustrated in FIGS. 8-13 is designed such that all of the termination elements 32 and, thus, each of the cables 14 around the spools 12 terminated with the termination elements 32 can be pulled at the same time. The modular cable pulling system 48 defines a plurality of carriers 50 that may be detachably coupled together, wherein each carrier 50 may be designed/structured based on the termination elements 32 used for the cabling to be deployed. According to one example embodiment of a coupling method, the carriers 50 may be snap-fit together. Other methods of mechanical attachment or linkage are certainly possible such as, e.g., a clevis and pinion attachment or an attachment using loops at the ends of the carriers.

Referring specifically now to FIGS. 8-10, a modular cable pulling system 48 that includes a plurality of carriers 50 carrying cable termination elements 32 in the form of multi-fiber (MPO) type connectors 38 is shown. Each MPO connector 38 is shown as being housed in an associated enclosure 39. The enclosure 39 is adapted for enclosing an end of a fiber optic cable and is used in certain applications to pull the MPO connectors 38 when the MPO connectors 38 are not attached to the carriers 50. The enclosures 39 may be used for pulling connectors such as the MPO connectors 38 through ducts or similar environments in setting up connectivity. The enclosure 39 includes a first member 41 that defines a first cavity that is adapted to receive a portion of the end of the fiber optic cable and further includes a second member 43 that is selectively engaged (e.g., snap-fit) to the first member, the second member 43 defining a second cavity. The enclosure 39 is adapted to transfer a tensile force applied to the enclosure 39 to the strength layer of the fiber optic cable terminated with the MPO connector 38. Further details relating to such cable-pulling enclosures 39 is described and illustrated in U.S. Application Publication No. 2010/0322584, the entire disclosure of which is incorporated herein by reference.

Still referring to FIG. 8, the carriers 50 are illustrated as being daisy-chained together using a snap-fit interlock system, wherein each carrier 50 defines a female snap-fit interlock structure 52 at a first end 54 and a male snap-fit interlock structure 56 at the opposite second end 58. The female and male snap-fit interlock structures 52, 56 may also be referred to as first and second interlock structures, respectively. FIG. 9 illustrates one of the carriers 50 of the modular cable pulling system 48 of FIG. 8 carrying two MPO type connectors 38 in a juxtaposed relationship. In this manner, four carriers 50 attached end to end may be used to unroll eight spools 12 of the packaging arrangement 10. FIG. 10 illustrates the carrier 50 of FIG. 9 in isolation without a cable termination element 32 coupled thereto.

As noted, one of the termination elements 32 that may be terminated to either end of the cable 14 on one of the spools 12 may be a multi-fiber connector 38 in the form of an MPO connector. The MPO connectors, as discussed above, may be enclosed in cable-pulling enclosures 39 when stored around the spools 12. MPO connectors are generally known in the art, and, thus, further details will not be discussed herein. As shown in FIG. 10, each carrier 50 associated with the modular cable pulling system 48 is designed to receive two MPO connector carrying enclosures 39 with a snap fit, wherein the MPO connector carrying enclosures 39 are stacked in a juxtaposed arrangement along their longitudinal axes A.

Each carrier 50 defines a body 60 having the first end 54, the second end 58, and a length L extending therebetween. At the first end 54, the female snap-fit structure 52 is defined. At the second, opposite end 58, the male snap-fit structure 56 that is configured to be coupled to the female snap-fit structure 52 of another carrier 50 is defined. The body 60 of the carrier 50 is configured to carry two MPO connectors 38 that are stacked along their longitudinal axes A. The body 60 defines a first side 62 including opposing flexible cantilever arms 64 and a post 66 protruding therefrom. The flexible cantilevers arms 64 and the post 66 are configured to receive the cable pulling enclosure 39 surrounding the MPO connector 38. The enclosure 39 defines an aperture 68 that is normally used for pulling cables attached to the enclosure 39. The post 66 of the carrier is configured to be inserted into the aperture 68 when coupling the enclosure 39 to the carrier 50. The body 60 defines a second side 70 having a similar configuration as the first side 62 for holding another MPO connector 38 along the same orientation. In the depicted embodiment, the carrier 50 includes a cable management structure 72 adjacent the female snap-fit structure 52. The cable management structure 72 is defined by a partial flexible ring 74 that is configured to retain cabling therewithin and keep the cabling close to the chain formed by the carriers 50.

FIGS. 11-13 illustrate a version of the modular cable pulling system 48 a having carriers 50 a that are designed for holding fiber optic cassettes 40/40 a. The carriers 50 a of the cable pulling system 48 a define a generally larger footprint than the connector holding carriers 50 of the system 48 of FIGS. 8-10. As shown in FIG. 13, each carrier 50 a again defines a first end 54 a having a female snap-fit structure 52 a and a second opposing end 58 a having a male snap-fit structure 56 a. As in the carrier 50 of FIGS. 8-10, the carrier 50 a is configured to hold two fiber optic cassettes 40/40 a in a juxtaposed position. Each carrier 50 a defines a first side 62 a for carrying one cassette 40/40 a and a second side 70 a for carrying a second cassette 40/40 a. The fiber optic cassette 40 shown in FIG. 11 is configured with SC type fiber optic adapters and the cassette 40 a shown in FIG. 12 is configured with LC type fiber optic adapters. The carrier 50 a shown in FIG. 13 may be used to carry either type of cassette 40 or 40 a. The carriers 50 a shown in FIGS. 11-13 also include cable management features 72 a similar to those discussed for the version in FIGS. 8-10.

As noted above, the cables 14 that are wound around the deployment packaging arrangement 10 may be terminated with various different telecommunications devices, depending upon the cable used and the connectivity arrangement. The fiber optic cassettes 40/40 a shown in FIGS. 11 and 12 are simply two example devices to which the ends of the cabling may be terminated.

An example of a fiber optic cassette 40 having SC type connection locations (e.g., adapters 42) is illustrated in FIGS. 16-18. It should be noted that the term “connection locations” may refer to any structure used to make a connection for continuing the signal on a cable such as a connector or an adapter used to connect two or more connectors together. As noted above, a cable 14 that is wound around a spool 12 of the packaging arrangement 10 and terminated to the cassette 40 may include multiple fibers and the cassette 40 is designed to separate and route the multiple fibers to connection locations for further connectivity. The cassette 40 includes a body 86 defining a front 88, a rear 90 and an interior 92. Body 86 further includes a top 94, a bottom 96, and sides 98, 100. Cassette body 86 defines a cable entry location 104 which in the illustrated embodiment is along rear 90. In the illustrated embodiment, cable 14 includes an outer jacket 110 and inner strength member 112 around inner fibers. Fibers extend past an end of jacket 110, and an end of strength member 112, and into interior 92 for connection with incoming connectors through the SC adapters 42.

As shown, cabling 14 that is terminated to the cassette 40 may include a boot 120 to provide strain relief at cable entry location 104. Cable 14 can flex away from cassette body 86 in the direction of arrow B, and may be protected from excessive bending by boot 120. Entry 104 is located close to corner 102, so that boot 120 and cable 14 is partially protected at entry 104 by being able to reside in a rear channel 106.

As shown in FIGS. 16-18, fiber optic adapters 42 may define the connections locations of the cassette 40 and may be arranged linearly and positioned along longitudinal axis C of the cassette body 86. In the given embodiment, the cable 14 at cable entry location 104 extends parallel to the longitudinal axis C, although some bending may be permitted relative to the longitudinal axis C.

In general, cassette 40 includes top 94 and bottom 96 which are generally parallel to each other and define the major surfaces of cassette body 86. Sides 98, 100, front 88, and rear 90 define the minor sides of cassette body 86. When the cassettes 40 are placed on the carriers 50 a, they are normally juxtaposed such that the minor sides of the bodies 86 are stacked, to minimize the footprint of the carriers 50 a. Similarly, if a cassette 40 is being stored within one of the flanges 16 of a spool 12, the cassette 40 may be laid in the storage compartment 30 with a major surface of the body 86 parallel to a flange's major cross-dimension to reduce thicknesses of the flanges 16 needed.

In the illustrated embodiment, adapters 42 are sized to receive front SC connectors. LC connectors can be used with appropriate sized adapters 42 a (as shown in the version of FIG. 11).

Cable 14 is connected to cable entry location 104 with a crimp tube 130 and a crimp ring 132 which crimps jacket 110 and strength member 112 to crimp tube 130. A small pocket 136 captures crimp tube 130 for retention with cassette body 86. Pocket captures hex end 138 of crimp tube 130 to retain cable 14 with cassette body 86.

Disposed within interior 92 of cassette body 86 may be a plurality of radius limiters 140 which can provide cable bend radius protection for the fibers disposed within interior 92. Cable radius limiters 140 can be in the form of discrete interior structures, and/or curved exterior surfaces which form around the front 88, rear 90, and sides 98, 100.

In the illustrated embodiment, the adapters 42 are formed in a block construction 150 having a front end 152 and an opposite rear end 154. Front end 152 includes a profile for receiving SC connectors. Front end 152 includes SC clips for clipping to an SC connector. Adapter block 150 also includes a rear clip 158 which clips to a hub and ferrule 160 (hub mounted to ferrule) which terminates each fiber exposed within interior 92 of cassette 40. Hub and ferrule 160 form a rear non-conventional connector 200. A split sleeve 162 is also provided for ferrule alignment between hub and ferrule 160 (rear connector) and the ferrule of the front SC connector.

In such a termination, fibers may be provided with excess length between crimp tube 130 and the rear connectors defined by the termination at hub and ferrule 160. Severe bending of the fibers is to be avoided. In the illustrated embodiment, the small size of the cassette 40 may require that some fibers reverse direction via limiters.

A cassette 40 a having LC adapters 42 a at the front of the body may be constructed similarly to the SC cassette 40 shown in FIGS. 16-18.

Further details of similar fiber optic cassettes 40/40 a are described in U.S. Patent Publication No. 2013/0089292, the entire disclosure of which is incorporated herein by reference.

Referring back to FIGS. 12-13, each carrier 50 a that is designed to hold the fiber optic cassettes 40/40 a defines a first side 62 a and a second side 70 a, each side having structures for snap-fitting the cassettes 40/40 a. At each side, a pair of posts 66 a protrude outwardly that are configured to fit within openings 85 on the cassette body 86. At each side, there is also a pair of flexible arms 64 a that are configured to flex in a front to back direction with respect to the body 60 a of the carrier 50 a in receiving the cassettes 40/40 a. As noted above, when the cassettes 40/40 a are placed on the carriers 50 a, the major dimensions are aligned with the longitudinal axes of the carriers 50 a for reducing the overall footprint of the carriers 50 a.

With the given modular cable pulling system 48, any number of termination elements 32 such as connectors 38 or cassettes 40/40 a may be placed on daisy-chained carriers 50/50 a and used to pull the cables 14 at the same time.

Now referring to FIGS. 14 and 15, another embodiment of a flange 16 a that may be used to form the packaging arrangement 10 of FIGS. 1-7 is illustrated. The flange 16 a of FIGS. 14-15 is similar in construction to the flange 16 of FIGS. 3-4 except that instead of including a removable scored area 46 for passing termination elements 32, it defines an opening or a passage 45 large enough to allow a termination element 32 (e.g., a fiber optic cassette 40 in this embodiment) to be pulled through the flange 16 a. The opening 45 is in addition to the smaller opening 44 a that allows a normally unterminated cable 14 to pass through. In this manner, if a cable 14 has been preterminated with a fiber optic cassette 40, the cassette 40 can be passed through the opening 45 before cable 14 is wound. And, if the cable 14 is postterminated after the cable end has passed through the cable opening 44 a, a fiber optic cassette 40 can be passed through the opening 45 from the second side 28 a to the first side 26 a after deployment of the cable 14 around the spool.

Also as shown in FIGS. 14-15, the second side 28 a of the flange 16 a may include retention features in the form of snap-fit interlock structures 29 for temporarily holding a termination element 32 such as a fiber optic cassette 40 within the storage compartment 30 a. The snap-fit interlock structures 29 may be defined by cantilevered arms 31. After the cable 14 around a spool has been paid out, the cassette 40 may be removed from the snapfit structures 29 and passed through the opening 45 from the second side 28 a toward the first side 26 a in completely removing the cabling from the packaging arrangement 10.

The packaging arrangements 10 described and illustrated herein may be used to store, transport, and deploy various types of telecommunications cables 14, including fiber optic cables. According to one example embodiment, 3.0 mm or 4.0 mm (ruggedized) fiber optic cabling with 6 or 12 fibers may be used. Other embodiments include the use of 1.2 mm, 1.7 mm, or 2.0 mm fiber optic cabling.

Various modifications and alterations of this disclosure will become apparent to those skilled in the art without departing from the scope and spirit of this disclosure, and it should be understood that the inventive scope of this disclosure is not to be unduly limited to the illustrative embodiments set forth herein.
